Don't display the "Detach template" and "Reset parameters" buttons to users with Read right

My user has Write right on Templates, and read on Workspaces.
When he goes on the Associated templates tab, he's displayed the "Detach template" and "Reset parameters" buttons. But when he clicks on it, he gets an error saying "You don't have the necessary permission to do the requested action" -> These buttons shouldn't be displayed to users that have only Read on the document.
